Exploring the Social Determinants of Health and Health Disparities in Traumatic Brain Injury: A Scoping Review

Traumatic brain injury (TBI) is a global health concern, that can leave lasting physical, cognitive, and/or behavioral changes for many who sustain this type of injury. Because of the heterogeneity of this population, development of appropriate intervention tools can be difficult. Social determinants of health (SDoH) are factors that may impact TBI incidence, recovery, and outcome. The purpose of this study is to describe and analyze the existing literature regarding the prevailing SDoH and health disparities (HDs) associated with TBI in adults. A scoping review, guided by the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) framework was used to explore three electronic databases-PubMed, Medline, and CINAHL. Searches identified peer-reviewed empirical literature addressing aspects of SDoH and HDs related to TBI. A total of 123 records were identified and reduced to 27 studies based on inclusion criteria. Results revealed race/ethnicity was the most commonly reported SDoH impacting TBI, followed by an individual's insurance status. Health disparities were noted to occur across the continuum of TBI, including TBI risk, acute hospitalization, rehabilitation, and recovery. The most frequently reported HD was that Whites are more likely to be discharged to inpatient rehabilitation compared to racial/ethnic minorities. Health disparities associated with TBI are most commonly associated with the race/ethnicity SDoH, though insurance status and socioeconomic status commonly influence health inequities as well. The additional need for evidence related to the impact of other, lesser researched, SDoH is discussed, as well as clinical implications that can be used to target intervention for at-risk groups using an individual's known SDoH.

Racial/Ethnic Disparity in Association Between Fetal Alcohol Syndrome and Alcohol Intake During Pregnancy: Multisite Retrospective Cohort Study

BACKGROUND

Alcohol consumption during pregnancy is associated with a range of adverse birth-related outcomes, including stillbirth, low birth weight, preterm birth, and fetal alcohol syndrome (FAS). With more than 10% of women consuming alcohol during pregnancy worldwide, it is increasingly important to understand how racial/ethnic variations affect FAS onset. However, whether race and ethnicity inform FAS risk assessment when daily ethanol intake is controlled for remains unknown.

OBJECTIVE

This study aimed to assess racial/ethnic disparities in FAS risk associated with alcohol consumption during pregnancy.

METHODS

We used data from a longitudinal cohort study (the Collaborative Initiative on Fetal Alcohol Spectrum Disorders) at 5 hospital sites around the United States of 595 women who consumed alcohol during pregnancy from 2007 to 2017. Questionnaires, in-person interviews, and reviews of medical, legal, and social service records were used to gather data on average alcoholic content (AAC) during pregnancy. Self-reports of maternal race (American Indian/Alaska Native [AI/AN], Asian, Native Hawaiian or other Pacific Islander, Black or African American, White, more than one race, and other) and ethnicity (Hispanic/Latino or not Hispanic/Latino), as well as FAS diagnoses based on standardized dysmorphological criteria, were used for analysis. Log-binomial regression was used to examine the risk of FAS associated with each 1-gram increase in ethanol consumption during pregnancy, stratified by race/ethnicity.

RESULTS

A total of 3.4% (20/595) of women who reported consuming alcohol during pregnancy gave birth to a baby with FAS. Women who gave birth to a baby with FAS had a mean AAC of 32.06 (SD 9.09) grams, which was higher than that of women who did not give birth to a baby with FAS (mean 12.07, SD 15.87 grams). AI/AN mothers with FAS babies had the highest AAC (mean 42.62, SD 8.35 grams), followed by White (mean 30.13, SD 4.88 grams) and Black mothers (mean 27.05, SD 12.78 grams). White (prevalence ratio [PR] 1.10, 95% CI 1.03-1.19), Black (PR 1.13, 95% CI 1.04-1.23), and AI/AN (PR 1.10, 95% CI 1.00-1.21) mothers had 10% to 13% increased odds of giving birth to a baby with FAS given the same exposure to alcohol during pregnancy. Regardless of race, a 1-gram increase in AAC resulted in a 4% increase (PR 1.04, 95% CI 1.02-1.07) in the chance of giving birth to a baby with ≥2 facial anomalies (ie, short palpebral fissures, thin vermilion border of the upper lip, and smooth philtrum) and a 4% increase (PR 1.04, 95% CI 1.01-1.07) in the chance of deficient brain growth.

CONCLUSIONS

The risk of delivering a baby with FAS was comparable among White, Black, and AI/AN women at similar levels of drinking during pregnancy. Regardless of race, a 1-gram increase in AAC resulted in increased odds of giving birth to a baby with facial anomalies or deficient brain growth.

Differential Expression of miRNAs Contributes to Tumor Aggressiveness and Racial Disparity in African American Men with Prostate Cancer

Prostate cancer is the leading cancer in incidence and second leading cause of cancer mortality in US men. African American men have significantly higher incidence and mortality rates from prostate cancer than European American men. Previous studies reported that the disparity in prostate cancer survival or mortality can be explained by different biological backgrounds. microRNAs (miRNAs) regulate gene expression of their cognate mRNAs in many cancers. Therefore, miRNAs may be a potentially promising diagnostic tool. The role of miRNAs in prostate cancer aggressiveness and racial disparity has not been fully established. The goal of this study is to identify miRNAs associated with aggressiveness and racial disparity in prostate cancer. Here we report miRNAs that are associated with tumor status and aggressiveness in prostate cancer using a profiling approach. Further, downregulated miRNAs in African American tissues were confirmed by qRT-PCR. These miRNAs have also been shown to negatively regulate the expression of the androgen receptor in prostate cancer cells. This report provides a novel insight into understanding tumor aggressiveness and racial disparities of prostate cancer.

Pediatric Invasive Meningococcal Disease, Auckland, New Zealand (Aotearoa), 2004-2020

New Zealand (Aotearoa) experienced a Neisseria meningitidis serogroup B epidemic during 1991-2006, and incidence remains twice that of other high-income countries. We reviewed clinical, laboratory, and immunization data for children <15 years of age with laboratory-confirmed invasive meningococcal disease in Auckland, New Zealand, during January 1, 2004-December 31, 2020. Of 319 cases in 318 children, 4.1% died, and 23.6% with follow-up data experienced sequelae. Children of Māori and Pacific ethnicity and those living in the most deprived areas were overrepresented. Eighty-one percent were positive for N. meningitidis serogroup B, 8.6% for serogroup W, 6.3% for serogroup C, and 3.7% for serogroup Y. Seventy-nine percent had bacteremia, and 63.9% had meningitis. In New Zealand, Māori and Pacific children are disproportionately affected by this preventable disease. N. meningitidis serogroup B vaccine should be included in the New Zealand National Immunization Schedule to address this persistent health inequity.

Racial and ethnic disparities in access to and enrollment in high-quality Medicare Advantage plans

OBJECTIVE

Racial and ethnic minority enrollees in Medicare Advantage (MA) plans tend to be in lower-quality plans, measured by a 5-star quality rating system. We examine whether differential access to high-rated plans was associated with this differential enrollment in high-rated plans by race and ethnicity among MA enrollees.

DATA SOURCES

The Medicare Master Beneficiary Summary File and MA Landscape File for 2016.

STUDY DESIGN

We first examined county-level MA plan offerings by race and ethnicity. We then examined the association of racial and ethnic differences in enrollment by star rating by controlling for the following different sets of covariates: (1) individual-level characteristics only, and (2) individual-level characteristics and county-level MA plan offerings.

DATA COLLECTION/EXTRACTION METHODS

Not applicable PRINCIPAL FINDINGS: Racial and ethnic minority enrollees had, on average, more MA plans available in their counties of residence compared to White enrollees (16.1, 20.8, 20.2, vs. 15.1 for Black, Asian/Pacific Islander, Hispanic, and White enrollees), but had fewer number of high-rated plans (4-star plans or higher) and/or more number of low-rated plans (3.5-star plans or lower). While racial and ethnic minority enrollees had lower enrollment in 4-4.5 star plans than White enrollees, this difference substantially decreased after accounting for county-level MA plan offerings (-9.1 to -0.5 percentage points for Black enrollees, -15.9 to -5.0 percentage points for Asian/Pacific Islander enrollees, and -12.7 to 0.6 percentage points for Hispanic enrollees). Results for Black enrollees were notable as the racial difference reversed when we limited the analysis to those who live in counties that offer a 5-star plan. After accounting for county-level MA plan offerings, Black enrollees had 3.2 percentage points higher enrollment in 5-star plans than White enrollees.

CONCLUSIONS

Differences in enrollment in high-rated MA plans by race and ethnicity may be explained by limited access and not by individual characteristics or enrollment decisions.

Socioeconomic correlates of health outcomes and mental health disparity in a sample of cancer patients during the COVID-19 pandemic

AIMS AND OBJECTIVES

To investigate socioeconomic, behavioural and healthcare delivery factors that are associated with health outcomes of cancer patients during the COVID-19 pandemic, especially among underserved cancer patients.

BACKGROUND

Cancer patients are at a higher risk of adverse physical and mental health outcomes during the pandemic than those without cancer.

DESIGN

Cross-sectional online survey. We followed the Strengthening the Reporting of Observational Studies in Epidemiology (STROBE) reporting guidelines in this study.

METHODS

The sample comprised 322 individuals diagnosed with incident cancer between January 2019 and January 2020. Demographically, 64% were female, 49% had a college degree, 12% were African American, and 88% were White (77% of the Whites were from metropolitan and 23% from nonmetropolitan areas). Descriptive analysis and multivariable regression analyses of global health status, depression and irritability were performed.

RESULTS

After adjusting for demographic variables and comorbidity, the feelings of loneliness, crowded living space, lower confidence in taking preventive measures and less satisfaction with telehealth visits were significantly associated with poorer global health, depression and irritability. Daily exercise was associated with better global health, and difficulty in getting medicine was associated with depression and irritability. Moreover, African Americans who felt lonely reported more depression and irritability and those who had less confidence in taking preventive measures reported more irritability than Whites. Respondents having low income and feeling lonely reported more depression than others.

CONCLUSIONS

In this study, socioeconomic factors (e.g. loneliness or crowded living conditions) were as important to health outcomes during the pandemic as behavioural (e.g. prevention and exercises) and quality-of-care factors (e.g. telehealth, access to medicine). Disparity was more pronounced in the mental health of African Americans and those with low incomes.

RELEVANCE TO CLINICAL PRACTICE

Healthcare providers should promote social support and physical activity for improving health and reducing mental health disparities among cancer patients.

A boot camp translation of Alzheimer's disease in Hispanic/Latino communities

Introduction

Hispanics/Latinos (H/Ls) are significantly underrepresented in Alzheimer's disease (AD) research participant samples. This exclusion limits our interpretation of research findings and understanding of the causes of brain health disparities. The Engaging Communities of Hispanics/Latinos for Aging Research (ECHAR) Network was created to engage, educate, and motivate H/Ls for participation in brain aging research by addressing several barriers to inclusion, including health literacy and AD-related communication.

Methods

We used a novel community-engaged method-Boot Camp Translation (BCT)-to translate medical jargon into action-based, community-relevant messages. H/L community members (n = 39) were recruited from three cities to work with local research teams and co-develop culturally responsive AD-related messaging. BCT meetings leveraged various techniques to identify key messages, the target audience for the messages, and methods to disseminate these messages. Themes were constructed collaboratively between BCT facilitators and community members as the group iteratively refined the conceptual framework and language for the main messages, with the goal to make AD messaging accessible for H/L community members.

Results

H/L community members showed significant improvements in subjective understanding (Cohen's d = 0.75; P < 0.001) and objective knowledge of Alzheimer's disease (Cohen's d = 0.79; P < 0.001) at BCT completion. H/L community members identified key messages that converged for all three cities. These were related to reducing stigma, emphasizing brain health and risk mitigation, and acknowledging the impact of AD on multi-generational families/households. Participants also recommended sharing these messages with H/Ls across the lifespan using multi-media avenues.

Discussion

The collaborative efforts identified culturally responsive and community-relevant messaging that may help address health literacy barriers contributing to AD-related disparities in H/L communities.

HIGHLIGHTS

Hispanics/Latinos are underrepresented in Alzheimer's disease and related dementias (ADRD) research despite increased risk.Limited ADRD health literacy may act as a recruitment barrier.Boot Camp Translation (BCT) is a process that targets health communication.We carried out BCT in three cities to co-develop ADRD messaging.Results highlight regional similarities and differences in ADRD communication.

A study of disparities in access to genetic care pre- and post-pandemic

We aimed to explore the delivery of pediatric genetic care before and during the COVID-19 pandemic and assess if disparities in care existed or emerged. We retrospectively reviewed the electronic medical record for patients 18 years old or younger seen in the Division of Pediatric Genetics between September 2019-March 2020 and April-October 2020. Outcomes included time between referral and new visit, recommendation and completion of genetic testing and/or follow-up visit within 6 months, and telemedicine versus in-person format. Outcomes were compared pre- and post-COVID-19 emergence across ethnicity, race, age, health insurance, socioeconomic status (SES), and use of medical interpretation services. Three hundred thirteen total records were reviewed with comparable demographics between cohorts. Cohort 2 had shorter times between referral and new visit, greater telemedicine utilization, and a greater proportion of testing completed. Younger patients tended to have shorter times between referral and initial visit. In Cohort 1, those with Medicaid insurance or no coverage had longer referral-initial visit times. In Cohort 2, there were differences in testing recommendation based on age. For all outcomes, no disparities were observed across ethnicity, race, SES, or use of medical interpretation services. This study characterizes the impact of the pandemic on pediatric genetics care delivery at our center and may have wider implications.

Systemic Inflammation Indices and Association with Prostate Cancer Survival in a Diverse Patient Cohort

There is a lack of investigations assessing the performance of systemic inflammation indices as outcome predictive tools in African Americans with prostate cancer. This study aims to assess the relationships between neutrophil-to-lymphocyte ratio (NLR), platelet-to-lymphocyte ratio (PLR), systemic immune-inflammation (SII), and systemic inflammation response index (SIRI) with survival outcomes among 680 diverse men with prostate cancer. Routine blood results were collected from self-identified African American and European American patients. We applied multivariable Cox regression modeling to examine the associations of systemic inflammation indices with overall and prostate cancer-specific survival. The median survival follow-up was 5.9 years, with 194 deaths. NLR, SII, and SIRI, but not PLR, showed associations with all-cause and prostate cancer-specific mortality when coded as dichotomized and continuous variables. NLR and SIRI were significantly associated with prostate cancer-specific mortality among all men (hazard ratio (HR) 2.56 for high vs. low NLR; HR 3.24 for high vs. low SIRI) and African American men (HR 2.96 for high vs. low NLR; HR 3.19 for high vs. low SIRI). Among European Americans, only SII showed an association with prostate cancer-specific survival. These observations suggest that inflammation indices merit further study as predictors of prostate cancer mortality.

Developing a Community-Oriented and Place-Based Strategy to Improve COVID-19 Vaccine Accessibility

Objective To address the challenges of inequitable access to the COVID-19 vaccines, Kaiser Permanente Southern California developed a community-oriented and geographic vaccine strategy combining clinical data, community data, and predictive models to identify ZIP codes requiring increased resources to achieve equitable vaccine receipt. Study Design This is a quality-improvement implementation study. Methods The authors developed hot-spot maps for southern California service areas to assist clinicians in identifying specific ZIP codes to increase vaccination efforts. Data inputs for these hot spots included COVID-19 incidence, hospitalization, ecologic variables of social determinants of health, and predictive models of vaccine penetrance. Partnering with community organizations, vaccine penetrance was improved by targeting hot spots with pop-up clinics, mobile health vehicle visits, extending facility hours, and sending tailored text messages. Results By the end of 2021, Kaiser Permanente Southern California achieved a 70% vaccination rate in 83% of 670 ZIP codes it serves, resulting in a total vaccination rate of 81% in 2021. Further, more than 2 out of 3 individuals receiving a vaccine through the hot-spot guided mobile health vehicle were Hispanic or Black. The hot-spotting approach produced a refreshed monthly dashboard of hot spots in 7 counties covering over 670 ZIP codes to help decision makers better understand and improve vaccination in targeted communities. Conclusion The hot-spot methodology produced monthly lists of ZIP codes requiring additional health-care resources and vaccination strategies. This was a feasible place-based approach to mitigating disparities in vaccine uptake in historically disinvested communities that may be readily applied to other areas of care.

Contraceptive Access and Use Among Undergraduate and Graduate Students During COVID-19: Online Survey Study

BACKGROUND

The COVID-19 pandemic led to widespread college campus closures in the months of March to June 2020, endangering students' access to on-campus health resources, including reproductive health services.

OBJECTIVE

To assess contraceptive access and use among undergraduate and graduate students in North Carolina during the COVID-19 pandemic.

METHODS

We conducted a cross-sectional web-based survey of undergraduate and graduate students enrolled at degree-granting institutions in North Carolina. Participants were recruited using targeted Instagram advertisements. The survey queried several aspects of participants' sexual behavior, including sex drive, level of sexual experience, number of sexual partners, digital sexual experience, dating patterns, and types of contraception used. Participants were asked to compare many of these behaviors before and after the pandemic. The survey also assessed several sociodemographic factors that we hypothesized would be associated with contraceptive use based on prior data, including educational background, sexual orientation and gender minority status (ie, lesbian, gay, bisexual, transgender, queer), health insurance status, race, ethnicity, degree of sensation seeking, religiosity, and desire to become pregnant.

RESULTS

Over 10 days, 2035 Instagram users began our survey, of whom 1002 met eligibility criteria. Of these 1002 eligible participants, 934 completed the survey, for a 93% completion rate. Our respondents were mostly female (665/934, 71%), cisgender (877/934, 94%), heterosexual (592/934, 64%), white (695/934 75%), not Hispanic (835/934, 89%), and enrolled at a 4-year college (618/934, 66%). Over 95% (895/934) of respondents reported that they maintained access to their preferred contraception during the COVID-19 pandemic. In a multivariable analysis, participants who were enrolled in a 4-year college or graduate program were less likely to lose contraceptive access when compared to participants enrolled in a 2-year college (risk ratio [RR] 0.34, 95% CI 0.16-0.71); in addition, when compared to cisgender participants, nonbinary and transgender participants were more likely to lose contraceptive access (RR 2.43, 95% CI 1.01-5.87). Respondents reported that they were more interested in using telehealth to access contraception during the pandemic. The contraceptive methods most commonly used by our participants were, in order, condoms (331/934, 35.4%), oral contraception (303/934, 32.4%), and long-acting reversible contraception (LARC; 221/934, 23.7%). The rate of LARC use among our participants was higher than the national average for this age group (14%). Emergency contraception was uncommonly used (25/934, 2.7%).

CONCLUSIONS

Undergraduate and graduate students in North Carolina overwhelmingly reported that they maintained access to their preferred contraceptive methods during the COVID-19 pandemic and through changing patterns of health care access, including telehealth. Gender nonbinary and transgender students and 2-year college students may have been at greater risk of losing access to contraception during the first year of the COVID-19 pandemic.

Health Experiences of Sexual and Gender Minority People Living With Dementia and Their Care Partners: Protocol for a Scoping Review

BACKGROUND

People living with dementia and their care partners who identify as a sexual and gender minority (SGM) often experience specific health inequities and disparities due to discrimination related to age, cognitive impairment, and being SGM.

OBJECTIVE

The purpose of this scoping review is to identify, explore, and synthesize the state of the science regarding the health and health care experiences of SGM people living with dementia and their care partners. This review also aims to identify gaps in research and set forth key recommendations to improve the health and health care experiences of SGM people living with dementia and their care partners by advancing health equity through research, policy, and practice.

METHODS

The protocol follows the guidelines set forth by Joanna Briggs Institute protocol for scoping reviews. Steps of this framework that will be followed include (1) identifying the research question; (2) identifying relevant studies; (3) study selection; (4) charting the data; (5) collating, summarizing, and reporting the results; and (6) consultation. This scoping review will explore several electronic databases, including MEDLINE, Embase, CINAHL, AgeLine, PsychINFO, and Scopus. Health librarians will conduct the initial search for articles that are in English, include people living with dementia who identify as SGM, SGM people living with dementia and their care partners, or SGM care partners caring for people with dementia. Studies must be peer reviewed and focus on the phenomenon of interest, which is the health and health care experiences of participants. Covidence will be used to review abstracts and full-text articles and to screen articles. After the search has been completed, 2 independent reviewers will screen article titles and abstracts to identify eligibility. Discrepancies will be discussed and decided upon by the 2 reviewers. Relevant studies will be collected, and data will be extracted and charted to summarize key findings. Key findings will be presented to a community stakeholder group of SGM care partners and people living with dementia, and a listening session will be convened.

RESULTS

This scoping review will identify the state of the science of health and health care experiences of people living with dementia and their care partners who identify as SGM. We will identify gaps and provide recommendations to inform future research, policy, and practice to improve health and health care experiences of SGM people living with dementia and their care partners.

CONCLUSIONS

Little is known about people living with dementia and their care partners who identify as SGM. This scoping review will be one of the first to identify the health and health care experiences of people living with dementia and their care partners who identify as SGM. The results of this review will be used to guide future interventions and to inform future policy and practice to improve health care and reduce health disparities in this population.

COVID-19 Vaccine Acceptance Among Korean American Immigrants in the United States: A Qualitative Study

INTRODUCTION

Immigrant populations in the United States are at increased risk of reduced COVID-19 vaccine acceptance. Currently, no qualitative research focuses on COVID-19 vaccine acceptance among Korean American immigrants (KAIs). This phenomenological study aims to uncover needs, beliefs, and practices that may affect COVID-19 vaccine acceptance within this immigrant group.

METHOD

Twelve study participants answered 10 semi-structured interview questions. Inclusion criteria for participants are as follows: (a) above 18 years, (b) has immigrated from Korea, and (c) can understand and speak English. Interview data were analyzed using Colaizzi's data analysis method.

RESULTS

Eight themes emerged from the study. Themes included apprehension and indifference, disruption of normalcy, patterns of acceptance, duty to protect, fear of contagion, perceived self-efficacy, relief and safety, and acceptance of new normal.

DISCUSSION

Findings from this study can inform health care professionals of cultural factors related to COVID-19 vaccine acceptance and health promotion behaviors among the KAIs.

Investigation of Factors Contributing to Racial Differences in Sport-Related Concussion Outcomes

OBJECTIVE

Following sport-related concussion (SRC), early studies have demonstrated racial differences in time-to-clinical-recovery; however, these differences have not been fully explained. We sought to further explore these associations by considering possible mediating/moderating factors.

METHODS

Data from patients aged 12-18 years diagnosed with SRC from 11/2017-10/2020 were analyzed. Those missing key data, lost to follow-up, or missing race were excluded. The exposure of interest was race, dichotomized as Black/White. The primary outcome was time to clinical recovery (days from injury until the patient was either deemed recovered by an SRC provider or symptom score returned to baseline or zero.) RESULTS: A total of 389 (82%) White and 87 (18%) Black athletes with SRC were included. Black athletes more frequently reported no SRC history (83% vs. 67%, p=0.006) and lower symptom burden at presentation [median total Post-Concussion Symptom Scale (PCSS) 11 vs. 23, p<0.001] than White athletes. Black athletes achieved earlier clinical recovery (HR=1.35, 95%CI 1.03-1.77, p=0.030), which remained significant (HR=1.32, 95%CI 1.002-1.73, p=0.048) after adjusting for confounders associated with recovery but not race. A third model adding initial PCSS nullified the association between race/recovery (HR=1.12, 95%CI 0.85-1.48, p=0.410). Adding prior concussion history further reduced the association between race/recovery (HR=1.01, 95%CI 0.77-1.34, p=0.925).

CONCLUSIONS

Overall, Black athletes initially presented with fewer concussion symptoms than White athletes, despite no difference in time-to-clinic. Black athletes achieved earlier clinical recovery following SRC, a difference explained by differences in initial symptom burden and self-reported concussion history. These crucial differences may stem from cultural/psychological/organic factors.

Molecular Subtypes of Head and Neck Cancer in Patients of African Ancestry

PURPOSE

The purpose of this study was to better understand the complex molecular biomarkers and signatures of head and neck cancer (HNC) among Black patients and identify possible molecular changes associated with HNC disparities.

EXPERIMENTAL DESIGN

Molecular subtypes and genomic changes in HNC samples from patients of African and European ancestry in The Cancer Genome Atlas, Memorial Sloan Kettering Cancer Center, Broad Institute, MD Anderson Cancer Center, and John Hopkins University were identified. Molecular features (genomic, proteomic, transcriptomic) associated with race and genomic alterations associated with clinical outcomes were determined. An independent cohort of HNC tumor specimens was used to validate the primary findings using IHC.

RESULTS

Black patients were found to have a younger age at diagnosis, more aggressive tumor types, higher rates of metastasis, and worse survival compared with White patients. Black patients had fewer human papillomavirus-positive tumor types and higher frequencies of laryngeal subtype tumors. Higher frequencies of TP53, MYO18B, KMT2D, and UNC13C mutations and a lower frequency of PIK3CA mutations were observed in Black patients. Tumors of Black patients showed significant enrichment of c-MYC and RET-tyrosine signaling and amplifications. A significant increase in tumor expression of c-MYC in Black patients was observed and was associated with poor survival outcomes in the independent cohort.

CONCLUSIONS

Novel genomic modifications and molecular signatures may be related to environmental, social, and behavioral factors associated with racial disparities in HNC. Unique tumor mutations and biological pathways have potential clinical utility in providing more targeted and individualized screening, diagnostic, and treatment modalities to improve health outcomes.

Health status and Healthcare Access of Southeast Asian refugees in the United States: An integrative review

OBJECTIVE

Since 2010, more than 527,000 refugees have resettled in the United States (US), most from Asia, fleeing war, violence, and persecution. However, there is little research that integrates findings about health among Southeast Asian refugees (SEAR).

DESIGN

We conducted an integrative review of studies that examined health status, risk factors, and barriers to healthcare access among SEAR in the US. We synthesized findings of studies published from 1980, when the Refugee Act was enacted, to 2022 using five databases. We reviewed 20 articles and data were extracted into a table for synthesis.

RESULTS

Participants were from Cambodia, Vietnam, Laos, Burma and the Thailand-Myanmar border. Hypertension (12%-64%), hypercholesterolemia (37%-39%), diabetes (0.6%-27%), heart disease (7%), bone and muscle problems (23%-50%), and chronic pain (8%-51%) were most common physical health problems; and PTSD (45%-86%) and depression (20%-80%) were the most common mental health problems. Trauma, resettlement stress, lack of community or religious engagement were associated with mental health problems. Language differences, transportation, and lack of health insurance were the most significant obstacles to receiving healthcare.

CONCLUSION

SEAR experienced worse physical and mental health than the general US population. Different patterns of disease were identified depending on gender, time settled in the US, and ethnic group. Qualitative and longitudinal studies will elucidate refugees' experience and should guide interventions.

Influence of Urbanization on the Spatial Distribution of Associations Between Air Pollution and Mortality in Beijing, China

This study investigated the influence of urbanization on the intra-city spatial distribution of associations between air pollution and mortality in Beijing, China. First, we utilized the generalized additive model to establish the exposure-response associations of PM_2.5, O₃, with nonaccidental and cardiorespiratory mortality between urban and suburban areas. Second, we assessed district-specific air pollution-related mortality and analyzed how these associations were affected by the degree of urbanization. Finally, we analyzed the changes in air pollution-related mortality before and after the enforcement of the Air Pollution Prevention and Control Action Plan (referred to as the Action Plan). The effect estimates of PM_2.5 for nonaccidental mortality were 0.20% (95% CI: 0.12-0.28) in urban areas and 0.46% (95% CI: 0.35-0.58) in suburban areas per 10 μg/m³ increase in PM_2.5 concentrations. The corresponding estimates of O₃ were 0.13% (95% CI: -0.04-0.29) in urban areas and 0.34% (95% CI: 0.12-0.56) in suburban areas per 10 μg/m³ increase in O₃ concentrations; however, the difference between the estimates of O₃ in urban and suburban areas was not statistically significant. The district-specific results suggested that the estimated risks increased along with urban vulnerability levels for the effects of PM_2.5. Implementing the Action Plan reduced the mortality risks of PM_2.5, but the risks of O₃ increased in some districts. However, the difference in the estimates between the pre- and post-emission reductions was not statistically significant. Our study indicated that populations living in less urbanized areas are more vulnerable to the adverse effects of air pollution in Beijing, particularly for PM_2.5.

Readability and Quality of English and Spanish Online Health Information about Cochlear Implants

OBJECTIVE

According to the American Medical Association, Internet web site health information should be written at or below a 6th grade reading level. The purpose of this study was to evaluate the readability and quality of cochlear implant web site health information.

STUDY DESIGN

Cross-sectional web site analysis.

SETTING

Four Internet search engines involving the top 200 web sites (English and Spanish).

INTERVENTION/METHODS

"Cochlear implant" was queried in four Internet search engines, and the top 200 English and Spanish web sites were aggregated. After removing duplicates, the web sites were evaluated for readability by using the following validated online readability calculators: Flesch Reading Ease score for English web sites and the Fernandez-Huerta Formula for Spanish web sites. Information quality was assessed using the validated DISCERN quality criteria and the presence of Health on the Net Code of Conduct (HONcode) certification.

RESULTS

A total of 80 non-industry-sponsored (43 English and 37 Spanish) and 11 industry-sponsored (4 English and 7 Spanish) cochlear implant health information web sites were included in the study. English web sites were written at a higher reading level (mean = 50.88, SD = 11.98) compared with Spanish web sites (mean = 59.79, SD = 6.04) ( p < 0.01). For both English and Spanish web sites, these scores correlate to the reading level of the average 10th to 12th grade student. Only 12% of Spanish web sites and 27% of English web sites were HONcode certified. The average DISCERN quality score was 41.67 for English web sites and 43.46 for Spanish, indicating significant concerns for quality. There was no association found between readability and quality of the web sites analyzed.

CONCLUSIONS

Patient-directed English and Spanish web sites regarding cochlear implantation were written at reading levels that significantly exceed those recommended by the AMA.

High Psychosocial Burden Relates to Poorer Antiretroviral Treatment Adherence Among Black/African American People with HIV

Black/African American communities continue to be disproportionately impacted by HIV with Black people with HIV (PWH) exhibiting poorer outcomes along the HIV treatment cascade. Psychosocial burden may, in part, explain these health disparities among PWH. We implemented a culturally adapted intervention [individualized Texting for Adherence Building (iTAB)] to improve ART adherence among 89 Black PWH in San Diego, CA. We aimed to (1) characterize psychosocial risk factors (depression, negative life events, discrimination, medical mistrust) hypothesized to be barriers to HIV outcomes among Black PWH and (2) determine if these factors influence intervention engagement, HIV outcomes, and self-reported physical and mental health. We identified three levels of psychosocial burden (low, moderate, high) through hierarchical cluster analysis. Participants in the high burden cluster (n = 25) experienced the highest levels of depression, negative life events, and discrimination, in addition to the poorest intervention outcomes, HIV outcomes, and physical and mental health compared to low and moderate burden clusters. Participants in the low (n = 29) burden cluster had less medical mistrust than the moderate (n = 34) and high burden clusters, but low and moderate clusters did not differ on any outcomes. Overall, self-reported ART adherence was 83%, which is above estimates of ART adherence in the Western region of the United States. The iTAB intervention shows promise in improving HIV-related outcomes among Black PWH with low to moderate psychosocial burden; however, additional supports may need to be identified for those with high psychosocial burden.

Sexual Health Interventions for Racial/Ethnic Minorities Using Community-Based Participatory Research: A Systematic Review

BACKGROUND

Racial/ethnic minorities (REMs) continue to carry the burden of sexual health disparities in the United States, including increased health risks and lower proportions of preventative care. Community-based participatory research (CBPR) has been useful in developing interventions aimed at reducing these disparities. Specifically, partnership with the target group members has resulted in more culturally relevant intervention strategies.

AIM

The purpose of this systematic review was to analyze the existing research on sexual health interventions targeting U.S. REMs that were developed using CBPR, to highlight the role target group members played in the development of these interventions, and to explore the benefits and outcomes of these partnerships.

METHOD

Preferred Reporting Items for Systematic Review and Meta-Analyses (PRISMA) guided the search of 46 thesauri terms for CBPR, sexual health, and REMs across six databases.

RESULTS

The initial search yielded 805 identified studies. After applying limiters, reviewing abstracts, and doing a full-text review, 24 appropriate studies were retained. The key findings indicated significant intervention outcomes such as increased health knowledge, attitude change, and behavioral intention that could reduce sexual risk-taking behaviors. Twelve studies detailed the methods for partnering with target group members to formulate interventions, highlighting the benefits related to recruitment, retention, and cultural relevance.

DISCUSSION

CBPR is well-positioned to address sexual health disparities among REMs. While community partnership strategies vary, the findings yield evidence that CBPR addressing sexual health disparities is achievable, can influence the effectiveness of interventions, and should be considered as an orientation in future sexual health research.

United Network for Organ Sharing (UNOS) Database Analysis of Factors Associated With Kidney Transplant Time on Waiting List

INTRODUCTION

 In the United States (U.S.), African Americans and other minority groups have longer wait times for kidney transplantation than Caucasians. To date, many studies analyzing time spent on the waitlist for each race/ethnicity have been done. However, there are few to no studies examining waitlist time after the 2019 policy changes to the geographic distribution of donated kidneys.

METHODS

Data collected from the National Organ Procurement and Transplantation Network database were used to analyze associations between race and time spent on the waitlist for a kidney transplant in the U.S. Additional sub-categorical data were analyzed to determine further associations and potential covariates, such as gender, age, citizenship, primary source of payment, region of transplant center, BMI, Kidney Donor Profile Index (KDPI), renal diagnosis, and presence/type of diabetes. Data were analyzed using odds ratios and validated by Bonferroni-Holm's corrected chi-square tests at confidence intervals of 95% to determine if there are statistically significant differences between transplant time spent on the waitlist and ethnicity, as well as age, diagnosis category, region of transplant center, and KDPI.

RESULTS

Statistically significant increased odds of remaining on the transplant list at two years existed for all non-white races/ethnicities, except those identifying as multiracial. Asian American candidates had the greatest odds of remaining on the waitlist greater than two years in comparison to white candidates: 1.51 times that of a patient categorized as white (odds ratio [OR] 1.51, confidence interval [CI] 1.44-1.57). African American/Black, (OR 1.38, CI 1.34-1.43) Pacific Islander (OR 1.38, CI 1.17-1.63), Hispanic candidates (OR 1.37, CI 1.32-1.41), and American Indian or Native Alaskan candidates (OR 1.23, CI 1.12-1.46) also had increased odds of remaining on the transplant waitlist greater than two years compared to white candidates.

DISCUSSION

In this study, ethnic disparities persisted as a barrier for non-white individuals receiving treatment for end-stage kidney disease, specifically in the context of time spent on the waitlist for a kidney transplant. Further research is needed regarding the causes of these disparities in time spent on the waitlist, such as cultural restrictions in organ donation, racial differences in parameters for organ match, and institutionalized racism in health care practitioners.

Examining Health Disparities in Orthopedic Care During COVID-19

BACKGROUND

Demographics and socioeconomic status affect the delivery of medical care resulting in healthcare disparities. The purpose of this study was to investigate the impact of COVID-19 on existing healthcare disparities, including access to healthcare in the outpatient orthopedic surgery clinic.

METHODS

The medical records of 3006 patients treated at the University of Kentucky Orthopedic Surgery Department prior to COVID-19 (April 2018, 2019), and during the COVID-19 pandemic (2020) were retrospectively reviewed for demographic data, distance to clinic, and type of visit. We then compared the total number of patient visits, new patient visits, telehealth visits, and the patient's insurance provider (public or private) between the time period prior to and during the pandemic.

RESULTS

During the COVID-19 pandemic, there were significant declines in the number of patients seen, new patient presentations, and publicly insured patients. Thirty-three percent of visits were telemedicine visits in 2020 compared to 0% pre-COVID (P < .0001). There was a lower proportion of initial visits in 2020 (P < .0001). The majority of patients paid via private/commercial insurance (1798, 59.8%), with a greater proportion paying via private/commercial insurance in 2020 (P < .001). The median average household income was increased in 2020 (P < .001).

DISCUSSION

While COVID-19 resulted in a significant decline in overall access to care, there were negative ramifications particularly on patients with new complaints and those of lower socioeconomic status. Future endeavors should be focused on correcting the obstacles to accessing care, exacerbated by the pandemic, that these vulnerable populations face.

Overcoming Access Barriers for Veterans: Cohort Study of the Distribution and Use of Veterans Affairs' Video-Enabled Tablets Before and During the COVID-19 Pandemic

BACKGROUND

During the COVID-19 pandemic, as health care services shifted to video- and phone-based modalities for patient and provider safety, the Veterans Affairs (VA) Office of Connected Care widely expanded its video-enabled tablet program to bridge digital divides for veterans with limited video care access.

OBJECTIVE

This study aimed to characterize veterans who received and used US Department of VA-issued video-enabled tablets before versus during the COVID-19 pandemic.

METHODS

We compared sociodemographic and clinical characteristics of veterans who received VA-issued tablets during 6-month prepandemic and pandemic periods (ie, from March 11, 2019, to September 10, 2019, and from March 11, 2020, to September 10, 2020). Then, we examined characteristics associated with video visit use for primary and mental health care within 6 months after tablet shipment, stratifying models by timing of tablet receipt.

RESULTS

There was a nearly 6-fold increase in the number of veterans who received tablets in the pandemic versus prepandemic study periods (n=36,107 vs n=6784, respectively). Compared to the prepandemic period, tablet recipients during the pandemic were more likely to be older (mean age 64 vs 59 years), urban-dwelling (24,504/36,107, 67.9% vs 3766/6784, 55.5%), and have a history of housing instability (8633/36,107, 23.9% vs 1022/6784, 15.1%). Pandemic recipients were more likely to use video care (21,090/36,107, 58.4% vs 2995/6784, 44.2%) and did so more frequently (5.6 vs 2.3 average encounters) within 6 months of tablet receipt. In adjusted models, pandemic and prepandemic video care users were significantly more likely to be younger, stably housed, and have a mental health condition than nonusers.

CONCLUSIONS

Although the COVID-19 pandemic led to increased distribution of VA-issued tablets to veterans with complex clinical and social needs, tablet recipients who were older or unstably housed remained less likely to have a video visit. The VA's tablet distribution program expanded access to video-enabled devices, but interventions are needed to bridge disparities in video visit use among device recipients.

COVID-19 Vaccine Equity and Access: Case Study for Health Care Chatbots

BACKGROUND

Disparities in COVID-19 information and vaccine access have emerged during the pandemic. Individuals from historically excluded communities (eg, Black and Latin American) experience disproportionately negative health outcomes related to COVID-19. Community gaps in COVID-19 education, social, and health care services (including vaccines) should be prioritized as a critical effort to end the pandemic. Misinformation created by the politicization of COVID-19 and related public health measures has magnified the pandemic's challenges, including access to health care, vaccination and testing efforts, as well as personal protective equipment. Information and Communication Technology (ICT) has been demonstrated to reduce the gaps of marginalization in education and access among communities. Chatbots are an increasingly present example of ICTs, particularly in health care and in relation to the COVID-19 pandemic.

OBJECTIVE

This project aimed to (1) follow an inclusive and theoretically driven design process to develop and test a COVID-19 information ICT bilingual (English and Spanish) chatbot tool named "Ana" and (2) characterize and evaluate user experiences of these innovative technologies.

METHODS

Ana was developed following a multitheoretical framework, and the project team was comprised of public health experts, behavioral scientists, community members, and medical team. A total of 7 iterations of ß chatbots were tested, and a total of 22 ß testers participated in this process. Content was curated primarily to provide users with factual answers to common questions about COVID-19. To ensure relevance of the content, topics were driven by community concerns and questions, as ascertained through research. Ana's repository of educational content was based on national and international organizations as well as interdisciplinary experts. In the context of this development and pilot project, we identified an evaluation framework to explore reach, engagement, and satisfaction.

RESULTS

A total of 626 community members used Ana from August 2021 to March 2022. Among those participants, 346 used the English version, with an average of 43 users per month; and 280 participants used the Spanish version, with an average of 40 users monthly. Across all users, 63.87% (n=221) of English users and 22.14% (n=62) of Spanish users returned to use Ana at least once; 18.49% (n=64) among the English version users and 18.57% (n=52) among the Spanish version users reported their ranking. Positive ranking comprised the "smiley" and "loved" emojis, and negative ranking comprised the "neutral," "sad," and "mad" emojis. When comparing negative and positive experiences, the latter was higher across Ana's platforms (English: n=41, 64.06%; Spanish: n=41, 77.35%) versus the former (English: n=23, 35.93%; Spanish: n=12, 22.64%).

CONCLUSIONS

This pilot project demonstrated the feasibility and capacity of an innovative ICT to share COVID-19 information within diverse communities. Creating a chatbot like Ana with bilingual content contributed to an equitable approach to address the lack of accessible COVID-19-related information.

The Impact of Social Determinants of Health on Meningococcal Vaccination Awareness, Delivery, and Coverage in Adolescents and Young Adults in the United States: A Systematic Review

Vaccines remain a fundamental intervention for preventing illness and death. In the United States, suboptimal vaccine uptake in adolescents and young adults has been observed for meningococcal conjugate (MenACWY) and serogroup B meningococcal (MenB) vaccines, particularly among marginalized communities, despite current recommendations by the Advisory Committee on Immunization Practices. A systematic literature search was conducted in the MEDLINE and MEDLINE In-Process, Embase, Cochrane, PsychInfo, and CINAHL databases to identify both drivers of, and barriers to, MenACWY and MenB vaccine uptake in adolescents and young adults. A total of 34 of 46 eligible studies that presented outcomes stratified by race/ethnicity, geography, and socioeconomic status were selected for review. Results showed MenACWY and MenB vaccination coverage in adolescents and young adults is impacted by racial/ethnic, socioeconomic, and geographic disparities. Gaps also exist in insurance for, or access to, these vaccines in adolescents and young adults. Moreover, there was variability in the understanding and implementation of the shared decision-making recommendations for the MenB vaccine. Disease awareness campaigns, increased clarity in accessing all meningococcal vaccines, and further research on the relationships between measures of marginalization and its impact on vaccine coverage in adolescents and young adults are needed to reduce the incidence of severe infections.
